I exported cross sections and a surface(apparently?) from Civil 3D into hecras. I set up a steady flow plan following some tutorials I found online. The problem I’m running in to is that the water elevations get ridiculously high towards the end of my stream/last cross sections, almost like the water is dammed up at the end. Just going through the cross sections the water elevations seem relatively normal to begin with but then makes a lake at the end. I’m new to hecras so I’m not sure where to take it from here.
